Over the past ten years studies in animals and human have supported the links between inflammation and tumors. The inflammatory cells and agents found in tumors play an important role in the pathogenesis of malignant disease facilitating tumor growth, invasion and metastasis. This article reviewed the molecular mechanism of inflammatory action in promoting tumors and suggested that inflammatory cytokine network is more likely to contribute to immunosuppression than to mount an effective host anti-tumor response.

Inhibition of tumor neovascularization (angiogenesis) has become one of the novel therapeutic strategies for tumor, and natural inhibitor of angiogenesis has been highlighted in this field. Thrombospondin-1 (TSP-1), as an important extracellular matrix component which can influence endothelial cell adhesion, migration, and proliferation, is reported to be a potent inhibitor of angiogenesis in vivo. It will be valuable to use its active peptides or small fragments from TSP-1 in antiangiogenesis therapy.

PTEN is a candidate tumor suppressor which has sequence homology with dual-specificity phosphatase. PTEN is a multifunctional protein endowed with a phosphatase activity capable of dephosphorylating both tyrosine phosphate, serine/threonine phosphate residues on proteins and phospholipids of the phosphatidylinositol pathway. PTEN appears to be mutated at considerable frequency in several types of human tumors, including those from brain, breast, endometrium, and prostate. PTEN play an important role in pathogenesis of tumor, tumor cell invasion and metastasis. In this review, we will discuss the chemical structure of PTEN, its phosphatase activity, the ability of affecting signal transduction, and its mutational status in cancer.

The abnormality of the central noradrenergic system in Alzheimer’s disease has two cases: decrease or increase. The former is easy to be understood, because it is resulted from the outstanding forfeit of the noradrenergic neurons in the nucleus locus ceruleus (nLC); but the noradrenalin concentration does not change and enen increase, it seems to disagree with the loss of the noradrenergic neurons in the nLC. This article put emphasis on it, enumerated the related evidence and analyzed the possible causes. At present time, the drugs to increase noradrenalin is used mostly in clinic. This paper summarized it and put forth our own opinions.
